Right, but despite being hardware, it shouldn't be this expensive, that is not a reason to price it that high. If games were done properly on PC, then we wouldn't need either, as has been proven by the frame times between the console games and PC, which makes me sad. Have you ever played a new release on PC? It's a horrible experience in my opinion, and more often than not, there is never a patch that completely fixes performance issues with a game, but damn sure within a week you'll be able to spend your real money on in-game items, that's priority in the industry today.
To comment on what you said about FPS and Hz. You still benefit from the faster response time, that doesn't change depending on how FPS you're getting, FPS is literally the higher the smoother it gets, more FPS doesn't equal faster transitions, as one is dynamic and the other is static. While it may sound like a rant, I really don't like what they're doing at all, it's like game developers intentionally made their games worse, and helped develop G-Sync/FreeSync behind the scenes...
If people want good looking premium monitors, then buy VA. While this sounds completely off topic, this is really the direction the market should be going. With the new AHVA "gaming" panels, they sacrifice color for speed, as has been proven mutliple times. We're not exactly moving forward in the monitor industry...
